Firstly, thanks for the brilliant script
I've integrated into a Movable Type + Rightfields powered site I'm working on. Everything is working perfectly, but I have now noticed that the thumbnail process fails silently if the suffix (.jpg, .png etc) is in upper case. My original image.JPG will upload, but no thumbnails will be created. If I change the suffix back to lower case then it works as planned.
Any ideas? Thanks in advance
